OUTPUT: line 1: Encrypted message (ans) The following is the Hill Cipher encryption algorithm program in C++. WebPlayfair cipher is an encryption algorithm to encrypt or encode a message. It is the same as a traditional cipher. The only difference is that it encrypts a digraph (a pair of two letters) instead of a single letter. It initially creates a key-table of 5*5 matrix. The matrix contains alphabets that act as the key for encryption of the plaintext.
